ElasticSearch 上的批量请求返回消息"The bulk request must be terminated by a newline"

Question

我知道StackOverflow上已经有类似的问题，但没有一个能解决我目前的问题。

我正在使用ElasticSearch 6.7.0，我目前正在学习它的教程。目前，我卡在此步骤上，这需要我下载存储在文件accounts.json中的一些示例数据。以下是该文件的一小部分：

{"index":{"_id":"988"}}
{"account_number":988,"balance":17803,"firstname":"Lucy","lastname":"Castro","age":34,"gender":"F","address":"425 Fleet Walk","employer":"Geekfarm","email":"[e-mail]","city":"Mulino","state":"VA"}
{"index":{"_id":"990"}}
{"account_number":990,"balance":44456,"firstname":"Kelly","lastname":"Steele","age":35,"gender":"M","address":"809 Hoyt Street","employer":"Eschoir","email":"[e-mail]","city":"Stewartville","state":"ID"}
{"index":{"_id":"995"}}
{"account_number":995,"balance":21153,"firstname":"Phelps","lastname":"Parrish","age":25,"gender":"M","address":"666 Miller Place","employer":"Pearlessa","email":"[e-mail]","city":"Brecon","state":"ME"}

该文件保存在路径C:UsersMeDesktopaccounts.json 内。

我按照教程中的说明运行了以下命令：

PS C：\Users\Me\Downloads\curl-7.64.1-win64-mingw\bin> .\curl.exe -H "内容类型：applicati lhost：9200/bank/_doc/_bulk？pretty&refresh" --data-binary "C：\Users\Me\Desktop\accounts.json">

我收到此错误消息：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "illegal_argument_exception",
        "reason" : "The bulk request must be terminated by a newline [n]"
      }
    ],
    "type" : "illegal_argument_exception",
    "reason" : "The bulk request must be terminated by a newline [n]"
  },
  "status" : 400
}

为了解决这个问题，我转到文件末尾并通过按 Enter 插入了新行。但是，当我再次运行该命令时，出现了相同的错误消息。

如何解决此问题？

Answer 1

我将accounts.json文件移动到运行curl.exe的同一目录，并执行了以下命令：

.\curl.exe -H "Content-Type： applicati lhost：9200/bank/_doc/_bulk？漂亮&刷新" --data-binary "@accounts.json">

这一次，批量请求成功。

对于那些面临类似问题的人，请记住按 Enter 在文件末尾插入新行。如果这不起作用，请尝试将文件移动到另一个目录中。错误消息"批量请求必须通过换行符终止"可能会产生误导 - 您的文件可能根本没有格式错误;也许由于各种原因根本无法定位或访问它。

Answer 2

使用 "@C：\Users\Me\Desktop\accounts.json"

而不是 "C：\Users\Me\Desktop\accounts.json"

即

curl.exe -H "Content-Type: applicati lhost:9200/bank/_doc/_bulk?pretty&refresh" --data-binary "@C:UsersMeDesktopaccounts.json"
